Krishna Kumar, 

What began as a project management blog for Kumar has turned into a full-fledged learning site. In five years, SimpliLearn has garnered 40 global accreditations for 200 courses, and last year it had 200,000 users. It has become a popular destination for IT professionals for its 20- hour courses in big data, digital marketing, and analytics. Investors, who have infused $13 million, love Kumar’s cost control: He has lined up 2,000 expert tutors and 100 classrooms in the U.S. And he doesn’t have a single salesperson there.
